At a guess, the PostgreSQL you are trying to attach to is not running
under the same user account as Eclipse.

The Linux kernel only permits you to attach to a process with the same
user account as you by default, unless you are the root user. That's
what "if your uid matches the uid of the target process" refers to.

You'll have the same issue when attaching using gdb directly, this isn't
an Eclipse issue.

If you were debugging manually with gdb you'd often do something like
   sudo -u postgres gdb -p thepid

to run gdb as the same user id as the target process. (Avoid running gdb
as root whenever possible). Perhaps Eclipse lets you configure a prefix
command for gdb so you can do that with Eclipse and passwordless sudo?
